Abstract

The production of foam which occurs in many chemical and physical materials conversion processes can be avoided by performing the materials conversion process in an ascending jet reactor, including a baffle-free container with a tapering lower section, preferably a conical lower section, and a device for gas injection, and the contents of the reactor are thoroughly mixed by means of ascending jet circulation caused by gas injection.
